Somehow I have changed the default color palette for changing the colors of the clusters. How can I adjust the color palette used in hierarchical clustering?
I am using this to teach a class and display geographical clustering using latitude and longitude for the San Francisco Crime dataset. For whatever palette got chosen there isn't enough of a difference in the colors between the clusters to effectively display the changes in cluster size as you change the number of clusters.
Thank you very much, that did fix my problem. I had selected Viridis at some point and when you have a categorical variable with only two categories, the colors were too similar. I was able to select another sequence of colors for categorical variables.
